Goal of the project

The project aimed to:

  • Develop a secure and scalable e-commerce platform using Python for backend processing.
  • Implement containerized deployment with Docker and Kubernetes for high availability and fault tolerance.
  • Provide users with a seamless experience across devices.
  • Ensure safe payment handling with Stripe API for secure transactions.

Project Execution

Architecture

The application followed a containerized microservices-based architecture:

  1. Frontend:
    • Built using React.js to ensure a responsive and user-friendly interface.
    • Features included product browsing, user authentication, shopping cart management, and order tracking.
  2. Backend:
    • Developed with Flask, providing RESTful APIs for product management, user authentication, and order processing.
    • Implemented secure authentication using JWT and role-based access control.
  3. Payment Gateway:
    • Integrated Stripe API for processing payments securely, supporting credit/debit cards and wallet payments.
  4. Containerization and Orchestration:
    • Docker: Used to containerize the frontend, backend, and database services for consistent deployment across environments.
    • Kubernetes (EKS): Deployed on AWS EKS for orchestration, enabling automated scaling, load balancing, and fault recovery.
  5. Database:
    • PostgreSQL: Used to store user accounts, product data, and order histories.
    • Redis: Integrated for caching frequently accessed data, reducing response times.
  6. Cloud Hosting:
    • Hosted the application on AWS with the following components:
      • S3: For storing product images and static assets.
      • EKS: For managing the containerized application.
      • RDS: Used for the PostgreSQL database.
